Ordercode: D6162
IMPORTANT:
The manufacturer will not accept liability for any resulting damages caused by the non-observance of
this manual or any unauthorized modification to the system.
 Never let the power cord come into contact with other cables! Handle the power cord and all
connections with the mains with particular caution!
 Never remove warning or informative labels from the unit.
 Never use anything to cover the ground contact.
 Never leave any cables lying around.
 Do not insert objects into air vents.
 Do not connect this system to a dimmer pack.
 Do not switch the system on and off in short intervals, as this would reduce the system’s life.
 Do not open the device and do not modify the device.
 Do not drive the inputs with a signal level bigger than required to drive the equipment to full output.
 Do not plug mics into the console (or stage box) while phantom power is on. Also mute the monitor /
PA system when turning phantom power on or off. Allow the system to adjust for a couple of
seconds, before setting the input gains.
 Only use system indoors, avoid contact with water or other liquids.
 Avoid flames and do not put close to flammable liquids or gases.
 Always disconnect power from the mains, when system is not used. Only handle the power cord by
the plug. Never pull out the plug by tugging the power cord.

Always operate the unit with the AC ground wire connected to the electrical system ground.
 Make sure you do not use the wrong kind of cables or defective cables.
 Make sure that the signals into the mixer are balanced, otherwise hum could be created.
 Make sure you use DI boxes to balance unbalanced signals; All incoming signals should be clear.
 Make sure that the available voltage is not higher than stated on the rear panel.
 Make sure that the power cord is never crimped or damaged. Check the system and the power
cord from time to time.
 Please turn off the power switch, when changing the power cord or signal cable, or select the input
mode switch.
 Extreme frequency boosts in connection with a high input signal level may lead to overdriving your
equipment. Should this occur, it is necessary to reduce the input signal level by using the INPUT
control.
 To emphasize a frequency range, you do not necessarily have to move its respective control
upward; try lowering surrounding frequency ranges instead. This way, you avoid causing the next
piece of equipment in your sound path to overdrive. You also preserve valuable dynamic reserve
(“headroom”).
 Avoid ground loops! Always be sure to connect the power amps and the mixing console to the
same electrical circuit to ensure the same phase!
 If system is dropped or struck, disconnect mains power supply immediately. Have a qualified
engineer inspect for safety before operating.
 If the system has been exposed to drastic temperature fluctuation (e.g. after transportation), do not
switch it on immediately. The arising condensation water might damage your system. Leave the
system switched off until it has reached room temperature.
 If your Dap Audio device fails to work properly, discontinue use immediately. Pack the unit securely
(preferably in the original packing material), and return it to your Dap Audio dealer for service.
 Repairs, servicing and electric connection must be carried out by a qualified technician.
 For replacement use fuses of same type and rating only.
 WARRANTY: Till one year after date of purchase.
